B.3 Installing Cabinets on Antistatic Floor
This section describes how to install N68-22 cabinets on antistatic floor.
N800 series supports are required when you install N68-22 cabinets in an equipment
room furnished with antistatic floor.
B.3.1 Introduction to Supports and Guide rails
I. Supports
The supports are used to raise the cabinets so as to facilitate flooring and cabling in the
equipment room. The supports are welded by steel plates. Insulation pads should be
placed under the supports and insulation coverings should be placed around the
expansion bolts, so that the equipment is insulated from the ground before grounding
cables are connected in order to meet the insulation requirements effectively.
Figure B-31 shows N800 series supports.
